| Abstract: |
Particulate matter (PM) has been linked to numerous adverse health effects in humans, with exposure being a significant factor in cardiovascular diseases and increased rates of mortality and morbidity. This study analyzed the concentrations of PM1, PM2.5, and PM10 during a dust storm in Western India in January and February, primarily affecting Ahmedabad, Pune, and Mumbai. Under typical atmospheric conditions, the monthly average inhaled concentrations of PM1, PM2.5, and PM10 in Ahmedabad were 30, 65, and 117 µg/m3, respectively. In comparison, Mumbai recorded 41, 80, and 143 µg/m3, while Pune reported 62 and 100 µg/m3 for PM2.5 and PM10. During the dust storm, however, these levels rose sharply: Ahmedabad reached 72, 154, and 269 µg/m3, Mumbai escalated to 136, 310, and 544 µg/m3, and Pune increased to 150 and 251 µg/m3. The findings highlight the substantial elevation in PM exposure associated with dust storm events, underscoring their potential implications for air quality and public health in urban regions of Western IndiaThe study employed the Multiple-Path Particle Dosimetry (MPPD) model to deepen the analysis to evaluate age-specific particle deposition in the three cities. Coarse particles (PM10) predominantly settled in the head and tracheobronchial regions, whereas finer particles (PM2.5 and PM1) were mainly deposited in the pulmonary areas. PM2.5 deposition was observed to be highest in children, followed by the elderly and adults. A detailed lobar analysis indicated that the left lower lobes experienced the highest deposition, followed by the right and middle lobes. PM2.5 emerged as the dominant particle size fraction deposited across all lobes for individuals of all age groups, including infants, children, and adults. The findings underscore the critical role of PMs in lung deposition and their relevance in assessing health risks, such as oxidative stress and toxicity from particle accumulation. |
